1.1.4 How Nautilus Loggers Take Readings Each Nautilus data logger has an on-board temperature sensor that you can use to record ambient temperature. You can turn this monitoring capability on or off using software. Nautilus data loggers can store readings to memory using one of two sampling methods: 1. -
Page 9: How To Use Nautilus Loggers
Test You can directly read the values that your Nautilus data logger is sensing using the Realtime capability of TrendReader software. This test gives you the opportunity to check your logger setup and make any necessary changes before starting the logging session. -

If you are retrieving the logger from the field, bring it back immediately to your computer for analysis. In order to analyze your Nautilus logger's data, you must first transfer a backup copy of its data to your computer. To do this, see Backup in the TrendReader guide. After transferring your information to the computer, the data is automatically copied to disk and time and date stamped. - Page 11 Nautilus Data Loggers Fluids: Material Use with These Fluids Do NOT Use with These ACR Part # Fluids DuPont Dow Viton Petroleum Oils, Gasoline, Acetone, H2S, Hot Water, 21-0071 Transmission Fluid Amines Ethylen Propylene Alcohols, Brake Fluids, Petroleum Oils, Diester...

Page 13: Nautilus Software Driver
Nautilus Data Loggers Nautilus Software Driver TrendReader software uses a software driver to communicate with Nautilus data loggers. The software driver takes the form of two windows. The Status window, shown when you contact the logger, is used to display the settings currently stored in the data logger. The Setup window, shown when you select Edit Setup, is used to alter the current settings and apply the changes to the data logger. -

Nautilus Data Loggers To find out more about sample rates and to view a set of sample rate tables, see Appendix A Sample Rates. The Mode is the way the logger stores the data. The Average method stores an averaged reading of the data read every 8 seconds over the sample interval you have chosen if the sampling mode is set to Average (this does not apply to a sampling interval of 8 seconds). - Page 15 Nautilus Data Loggers Full. To set the compression method click on the Compression field and select ON. A run length compression method is used. Run length compression stores the reading plus the number of consecutive times the same reading was measured. This means that the logger will store 2 values to memory, the data value and a counter value.

1.3.1 Description The Nautilus 85 is a durable, robust data logger that can monitor temperature in a variety of applications but is particularly well suited for the food and beverage, biomedical, pharmaceutical, and industries with hostile or "wet" environments (i.e. wastewater treatment plant). -
Page 19: Troubleshooting
The individual sensor associated with your Nautilus 85 measures and records temperature only in one location. They do not, in any way, represent an overall reading. -
Page 20: Appendix A Nautilus 85/135 Sample Rates
The following tables list the maximum time spans over which your Nautilus will record readings. The time spans depend on the length of the sample rate. A Nautilus has a memory capacity of up to 32,640 readings when data compression not selected and up to 244,800 readings when data compression is selected. - Page 21 16 sec. 32 sec. 56 sec. 2 min. 4 min. 56 sec. 10 min. 20 min. 30 min.
